London, 20 April 2020 – Epsilogen (formerly IGEM Therapeutics), a global leader in the development of immunoglobulin E (IgE) antibodies to treat cancer, today announces that interim data from the ongoing phase 1 clinical study of MOv18 IgE will be presented at the forthcoming American Association for Cancer Research (AACR) Virtual Annual Meeting I, 27-28 April 2020. This study, funded, sponsored and conducted by Cancer Research UK’s Centre for Drug Development, is evaluating MOv18 IgE, a first-in-class IgE antibody, in patients with advanced cancer expressing folate receptor alpha (FR alpha). This receptor is known to be overexpressed on the surface of certain cancer cells, most commonly ovarian cancer. MOv18 IgE is the first therapeutic IgE antibody to enter clinical trials.

The presentation at the AACR meeting will be made by Professor James Spicer of King’s College London (KCL), UK, one of the scientific founders of Epsilogen and lead investigator of the phase 1 study. As announced separately today, Epsilogen has in-licensed MOv18 IgE from KCL, where it was originally developed in collaboration with Cancer Research UK.

This multi-centre, dose escalation, phase 1 study, enrols patients with histologically, or cytologically-proven, advanced, unresectable solid tumours where FR alpha expression on their tumour was detected in a previous biopsy. Patients are administered their allocated dose of MOv18 IgE by IV infusion. The primary objective of the study is safety and tolerability of the study drug. Secondary objectives are anti-tumour activity, as measured by the Response Evaluation Criteria in Solid Tumours (RECIST) and assessment of disease response, using CA 125 tumour marker.

Cancer Research UK has an impressive record of developing novel treatments for cancer. The Cancer Research UK Centre for Drug Development has been pioneering the development of new cancer treatments for more than 25 years, taking over 160 potential new anti-cancer agents into clinical trials in patients. It currently has a portfolio of around 20 new anti-cancer agents in preclinical development, Phase I or early Phase II clinical trials. Six of these new agents have made it to market including temozolomide for brain cancer, abiraterone for prostate cancer and rucaparib for ovarian cancer. Two other drugs are in late development Phase III trials.
